Answer to Question One: What is Tom's Net Monthly Salary?

What information is left to be found? We need to know the number of miles from Statesboro to Walterboro and the number of miles from Statesboro to Macon.Click here to go yahoo for a map and directios.

 

You can see that Tom it is 125.9 to Walterboro and 124.4 miles to Macon. So, Tom drives a total of 250.3 miles. But this is only one way. He drives 500.6 miles in one week, after travelling to both cities and returning (this is not including mileage inside of each city, which is minimal and not neccessary to consider). For work purposes, Tom travels 2002.4 miles per month. How much does it cost Tom in travel in ?

His truck gets 31 miles to the gallon and holds 20 gallons. Therfore, he can get . Therefore, Tom can do all of his driving in one tank of gas.

It costs Tom $1.40/gallon in gas. Therefore, it costs him (20)($1.40) = $28.00 to fill his truck up. So, it costs him $28.00 to drive to and from work in a week in which he only works two days. How many times in a month (only considering driving to and from work) should Tom have to fill up in a month?

By dividing the number of miles that Tom drives in a week by the number of miles he "gets" from one take of gas, we can find the number of time he has to fill up in one month.

Finding 3.23 tanks is the same as finding 323% of 20 gallons: (3.23)(20) = 64.6 gallons. This will cost Tom (64.6)($1.40) = $90.44/month.

We could have also arrived at this total cost for gas per month by using the fact that Tom spend $28 on one tank of gas. Therefore, it costs him $84 for three tanks of gas and ($1.40)(.23)(20) = $8.4 for the other .23 of a taking of gas. This also totals to $84+$6.44=$90.44

Tom brings home 65% of $400/week. Or, on a monthly basis, Tom brings home 65% of $1600.

Remember, x% means "x/100"

Remember, "of" means "multiply"

Therefore, 65% of 1600 can be translated as (.65)(1600)=$1040.00. This is how much Tom brings in on a monthly basis. If we subtract his monthly costs, $90.44, we find that his net monthly salary is $1040.00 - $90.44 = $949.56. This is $50.44 short of his monthly needs.
